The issue is hard to reproduce on my machine, but I could reproduce it in ~12 hours of non-stop testing in a loop. It reproduces even with wait_local_port_listen, so it must be something else. The log above (and my repro attempts) shows that it fails in a non-first test, but netserver starts only once, before the first test. If the failure was due to netserver not being ready, it would fail in the first test. I'll keep investigating. > Cheers, > Matt > -- > Sponsored by the NGI0 Core fund. >
